Scott Gregory advances 36 rankings to number eight on this week’s World Amateur Golf RankingTM after the biggest win of his life. The 21-year-old Englishman called winning the 121st Amateur Championship at Royal Porthcawl “a dream come true.”

Gregory arrived at Royal Porthcawl hoping to improve his world ranking so he could be eligible for the U.S. Amateur Championship. He not only achieved that goal, he earned spots in the Open Championship at Royal Troon next month, plus invites to the Masters and U.S. Open next year.

“I can’t believe I’m going to play in the Open Championship,” he said.

Gregory was the last man standing out of the 288 players who began the week. He defeated Robert MacIntyre 2&1 in the 36-hole final. The 19-year-old Scot jumps 24 places into the top 30 to 26th.

Scotland’s Connor Syme finished leading qualifier by two shots with a 6-under-par 136. Syme, who lost in the fourth round, advances five places to 34th.

Morikawa soars at Sunnehanna

American Collin Morikawa breaks into the top 30 after winning the rain-shortened Sunnehanna Amateur in style. Morikawa returned a bogey free 8-under-par 62 in the final round. His 11-under-par 199 gave him a three-shot victory. He becomes the world’s 29th best player with a rise of 16 rankings.

Top 20 movers

Poland’s Adrian Meronk is the only new top 20 player with a rise of 11 places to 11th after reaching the semi-final of the Amateur Championship.

Top 50 movers

Nick Hardy of the United States is the only player to break into the top 50. He moves seven places to 49th.
